براغي رأس سداسي مقاس 7/8-9 × 5 بوصات | فولاذ درجة 5 بزنك أصفر | خيط جزئي (15/عبوة)

These partially threaded hex heads grabbed tight into my metal frame without stripping, which was my main worry. The Grade 5 steel feels noticeably tougher than the standard hardware I've been using. A solid upgrade for heavy equipment assembly.

Had to fasten a few heavy equipment guards and these partially threaded bolts made the job a lot quicker since the smooth shank gives a clean grip in the bracket. The yellow zinc coating seems thick enough to resist rust, which is exactly what I needed for outdoor use.

The hex head on these grade 5 bolts grabbed my socket wrench perfectly, and the yellow zinc finish looks like it'll hold up well in my shop. They threaded smoothly into the equipment frame without any binding.
